Does any one know if the torque converter has a drain plug on it like some of the other tranny torque converters on GM rearwheel drive cars. i.e. caprice's.

No there isn't a drain plug.

not from the factory, a few aftemarkets do

Mike L told me there is a pressure port on the bottom of the bell housing. http://www.dieselplace.com/forum/showthread.php?t=39950
He didn't say if it would drain it completely or not.

thanks. just hoping for an easy way to do a complete fluid change. I guess I will try the circulate and add method.
